Black Fairy, the master is a female ghost

In a blink of an eye, fifteen days passed.

The weapon refining workshop produced a thousand waist badges one after another.

Lu Xunhuan saw that it was almost done, so he stopped working on it.

The 500 coins previously reserved by the wealthy people in the city have all been distributed and exchanged for silver notes.

Later, he asked the weapon refinery to continue processing and produce another 500 pieces, preparing to sell them piecemeal.

Now that a large amount of funds are in place, all work has been accelerated.

However, the relationship between him and Zhao Tongpan has become subtle now.

The Crown Prince decided to marry Zhao Lan, the daughter of Zhao Tongpan, to Lu Xunhuan. Everyone in the provincial government knew about it.

Zhao Tongpan still doesn't know that his daughter and Lu Xunhuan are still pretending to be a couple.

He thought that the two of them had already done something irreconcilable. After all, the prince later sent someone to collect the white towel that had been used to see blood, and he secretly showed it to him.

Naturally, he was unwilling to see his daughter become Mrs. Lu quietly. As a father and a prominent official in Baocheng, he certainly wanted to hold a grand wedding for his daughter.

He was waiting for Lu Xunhuan to take the initiative to propose holding a wedding ceremony.

But he waited and waited for half a month, but Lu Xunhuan didn't say a word.

Although he didn't show any emotion, he was extremely depressed in his heart.

What does Lord Lu mean by this? He took Lan'er and didn't say a word. He didn't even give a penny for the bride price?

If that were the case, it would be really embarrassing for him as a Tongpan, as it would be equivalent to Lu Xunhuan ignoring him.

But he was too proud to ask Lu Xunhuan in person, so he asked someone to find out what Lu Xunhuan was thinking.

On this day, Lu Xunhuan brought a group of officials to inspect the progress of tunnel excavation.

About 10,000 people gathered on both sides of the mountain, and under the guidance of water conservancy experts, they were busy digging and building embankments. The canal had already taken shape.

The tunnels were dug simultaneously from both sides of the mountain, and there was a clanging sound inside the cave.

When they hit the hard part, a large amount of firewood was sent in and set on fire, and thick smoke was often seen billowing from the cave entrance.

The scene was busy, tense and orderly.

Lu Xunhuan inspected the place and reminded people to pay special attention to safety to ensure that no accidents occurred.

The water conservancy official reported, "Sir, as we dig deeper, it becomes increasingly difficult to burn the canal. The smoke is so thick that we can't even stand still. We've made about a mile at each end, but we can't burn the remaining three miles in the middle. We can only chisel away bit by bit. This way, we can't guarantee a quick breakthrough."

Lu Xun Huan stroked his chin and thought for a moment before saying, "If it's truly impossible to burn it, don't force it. Evacuate the people and build a ditch outside first. I'll go back and think of a solution."

After the inspection, he didn't even have time to eat and immediately returned with a group of officials.

On the way, an official rode in the same carriage with him. The official asked quietly, "Sir, you married the daughter of the Tongpan, but why didn't you make any public announcement? You should at least publicly send some betrothal gifts to the Zhao Tongpan family and set a date for the wedding. Otherwise, the Tongpan will lose face."

Lu Xun Huan said, "I'm busy all day and really don't have time. Please tell Zhao Tongpan that I haven't forgotten this matter. Once everything is back on track and the Crown Prince returns to Yingzhou City, I will naturally give him an explanation."

The official nodded and said, "I will definitely inform the magistrate."

After returning to the city, he asked all the officials to return to the yamen, and he took Yun Zhongzi to find a firecracker shop in Baocheng.

The owner of the firecracker shop was shocked to see Lord Lu in person, thinking something had happened.

He hurried forward and bowed, "Lord Lu..."

Lu Xun Huan looked at the few firecrackers in the workshop and asked, "Where did you buy all this gunpowder?"

The shop owner replied, "Twenty miles outside the East City Gate, there's a saltpeter mine. Someone there has built a workshop specializing in producing gunpowder. I bought it from him. Sir, could there be an accident somewhere, causing injuries?"

Lu Xun Huan picked up a firecracker and looked at it. "If we make this thing bigger and turn it into a large explosive, its power should be able to blow up rocks, right?"

After hearing what he said, the shop owner understood what Lord Lu meant.

He said, "If you want to blow up a rock, first drill a hole in it, put in a fuse, then fill it with gunpowder. After it explodes, it should explode."

Lu Xun Huan asked, "What if the stone is extremely hard, the kind that sparks when you chisel it?"

The shop owner replied, "No matter how hard the stone is, it can be mined. It just requires a lot of tools. You can have the tool shop make some exceptionally hard iron chisels to drill holes in those stones. It may take a little longer than with ordinary stones, but with hard work, you can get it done."

Lu Xunhuan nodded: "So, social progress means technological progress in all aspects. Baocheng's ironmaking industry must make progress."

He said to the shop owner, "Please help me contact the man outside East City. I need a large amount of gunpowder for my mountain excavation. Ask him if he can supply it. If he can, please buy it for the state government. Raise the price a little and the state government will buy it from you."

The shop owner nodded quickly: "Okay, okay."

After leaving the firecracker shop, Lu Xunhuan went to the weapon forging workshop and had a conversation with the iron smelters, asking them to forge iron with higher strength and toughness in order to make harder and tougher iron rods.

Then, he returned to the government office and issued a notice to encourage technological innovation in all the weapon forging workshops in the city. Whoever could smelt iron with higher hardness and toughness would be rewarded by the state government.

He returned to the city like the wind, issued the notice, and then left the city like the wind to inspect the construction of the plank road.

The carriage swayed and bumped on the road, and he closed his eyes, pretending to practice.

Yun Zhongzi would occasionally ask a few questions about his progress in cultivating immortals.

Lu Xunhuan, like before, pretended to be making rapid progress.

And now, he pretended to be breaking through from the Tengyun Realm to the Huiyang Realm.

Of course, he had already calculated the pace of progress; it couldn't be too slow, nor too fast.

As long as one day he announced that he had entered the Huiyang Realm, he would no longer be afraid of Yun Zhongzi seeing his body glowing while practicing, and he could practice normally.

Although he had deliberately calculated the time, the progress of his cultivation that he reported still surprised Yun Zhongzi greatly.

Looking around the world, is there anyone in the history of the fairy world who is faster than Master Lu?

He had never heard of it.

Yun Zhongzi was already considered a genius in the world of immortal cultivation, and it took him three full years to break through to the Huiyang Realm.

As for Lu Xunhuan, it has been less than half a year since Mei Siya taught him how to cultivate immortality.

Could it be that the disciples of the sages were endowed with special abilities by the sages, and their cultivation of immortality must be ten or even a hundred times faster than that of ordinary disciples?

After inspecting outside for half a month, Lu Xunhuan returned to Baocheng.

Through continuous experimentation, the weapon forging workshops throughout the city finally made new progress and smelted harder and tougher iron.

Lu Xunhuan asked, feeling quite relieved.

There are always brave men when there is a big reward, and there are always masters among the people.

People in this world don’t understand what chemical elements are or what rare metals are.

However, they were able to collect special rocks and soil from the mountains and add them as auxiliary materials to iron smelting. Through continuous experimentation, they actually produced different alloy materials.

No one knows what elements are contained in the material. They only know that by adding a certain type of rock and soil, they can smelt harder and tougher iron.

In this world, this is considered a very good achievement.

After Lu Xunhuan took up his new position, he ordered the weapon forging workshop to quickly use that special iron to make a batch of iron chisels.

Afterwards, he returned to the provincial government office, personally wrote a commendation notice, posted it throughout the city, and took out 100,000 taels of silver as a reward to the five weapon refineries with the most outstanding contributions.

Such tangible rewards not only make the iron and steel industry happy, but also stimulate the accelerated transformation of new technologies in all walks of life.

After Lu Xunhuan rewarded the weapon refining workshop, he immediately went to find the firecracker shop owner and bought some gunpowder. He asked the officials to leave the city quickly and find some deserted places to blast rocks for experiments in order to estimate the depth of the holes to be drilled and the amount of gunpowder to be used.

During the days when Lu Xunhuan was waiting for the weapon forging workshop to make the iron chisel, there was a constant rumbling sound outside the city, attracting many people to watch the fun.

Once gunpowder is invented, it must be used properly to promote scientific and technological progress.

It is a huge invention that can change an era.
